NAIL-EXT EPECIEECATION forming part of Letters Application tiled January 18, i886.

To all whom, it may concern:

Be it known that I, Permis F. KING, of Kansas City, in Jackson county and State ot' Mi souri, have invented a certain newand useful Improvement in Nall-Extractors, otl which the following is afnll, clear. and exact descriping drawings, l'orining part ot' this specification, and in which Figure I is a perspective View of the tool. Figs. 2, 3, and 4 are detail side views illustraling the manner of using the tool, and Fig. 5 is a similar view showing another wayin which the tool maybe used.

A is the stein or lever-bar, which may he properly made ot' wrought or malleable iron.

B is the handle.

C is a shoe, slotted at c, to allow the passage ofthe bar A, and supported on aA pivot-bolt,` D, passing through the sides of the shoe and through the lever-bar A. The length ot' the slot c is sufficient to allow the lever A a limited movement on the pivot D. The movement of the lever is limited in the shoe, to pre ventthe pulling-jaws comingin actual contact, and to enable thelever and the curved fdlcrumthe drawing of the nail from the wood. The other arm, c2, of the shoe is slotted or mortised for the passage of the shank E of the jaw E. This shank is held in position in the mortise by a set-screw, F.

El is a ball on the end of the shank, said ball being of a size to form agood grip forthehand. The jaw E has a chisel-edge, c, which is fitted to cut a groove in the wood, and to engage the nail G beneath the head, as seen in Figs. 3, 4, and 5.

H is a set, which is fixed in a niortise or socket made in the end of the bar A. This set forms one of the gripping-jaws. It may be held in by the pivot-bolt D. The construction is such that the set may be replaced by another or may be removed for repointing.

The position of the tool when iirst applied to the nail is shown in Fig. 2, where I represents the wood in section. One hand is applied to the handle B of the bar A, and the other to the ball Ezof thejaw E. Then, without materially moving the leverbar A, the shank E of jaw E is moved in the direction- RACTOR.

shown by the arrow, which plows a channel, i, in the wood, and l'orces the jaw E against the nail below the head, as seen in Fig. 3. The lever-bar A is now moved iu the direction indicated by the arrow, which first forces the jaw H into the wood, and then lifts both jaws, with the nail, hy hearing on the curved arm casa t'ulcruni. (See Fig. 4.) The form ofthe arm c is such thatthe nail is drawn outward in almost a straight line.

In drawing the lighter class ot' nails, especially those haring heads, the hand may be removed t'roni the ball as soon as the jaw E has come in contact with the nail,as the weight ofthe ball is sufficient to maintain the hold of thejaw upon the nail.

When the tool is operated as shown in Fig. 5, the chisel-jaw E is tirst placed through the wood into engagement with the nail, and then, the leverbar A being moved in the direction of the arrow, the jaw H is first brought into engagement with the nail, as seen in Fig. 3, and then the nail drawn out. (See Fig. 4.) The end hI ot' the set H is rounded, so as to give a curved cuttingedge, It', as seen in Fig. 1, so as to prevent the jaw from slipping transversely from the nail. The same object would be accomplished by making t-he edge angular.

I have shown the shoe O as pivoted to the lever A; but this, though my preferred c0nstruction, is not absolutely essential, as the fulcrum bar or arm c might be rigidly attached to the lever A, the jaw E being hinged to the lever to operate substantially as set forth.

In the practical use of the tool the Wood shaving comes between thejaw E' and the nail, and prevents the wear upon the edge of the `raw.

It will be understood that no concussion of any kind is used in operating the tool, so that there is neither noise norjar.

It will be seen thatthere is nospring in the tool to get out ot' order.

The shank E, I have made of ordinary barsteel pointed up, as shown at E. and as the point wears the shank can beset down to compensate for the wear.

In adjusting the jaw E' for work it is so placed as to cut into the wood the required depth. While the jaw H is resting on the surface of the wood, then as the lever A is swung IOO I over on the fulcrum the jaw H is drawn down into the wood by the bearing of the jaw E up* on the nail..

I claim as my invention'- 1. The combination of the lever A, with removable jaw or set H, the fuicru r11-shoe carrying a curved bar, 0, and a projection, c', in which is held the weighted shank Eof the jaw E', substantially as and for the purpose set forth. l

2. The combination oflever A, with jaw H secured in its end, fulcrum-shoe C, pivoted to the lever having a curved fulcrum-arm, c. and a. projection, c', mortised to receive the shank E of the jaw E', said Shank beingdjnstablein 15 the mortise and secured by set-screw therein. 3. The combination of lever A, wit'hjaw H secured in its end, fulcrum-shoe C, pivoted to the lever having a curved fulcrum-arm, c, and

a projection, c', mortised to receive the shank 2o SAML. KNIGHT, BENJN. A. KNIGHT.
